Photo ID: 112712 Date Shot Photo By Tuesday, July 1, 2025 Kevin Morgan Location Times Viewed Tunnel 16 (MP 28.7, 698 ft) Jefferson County, CO 10 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Amtrak Tunnel 16 is one of the longer tunnels in the Tunnel District, just two feet shy of 700 feet long. As a result, there is some exhaust that builds up in the tunnel, and you can see a bit of that exhaust coming out of the tunnel toward the left as the westbound Zephyr continues west in the Tunnel District.

Photo ID: 112713 Date Shot Photo By Tuesday, July 1, 2025 Kevin Morgan Location Times Viewed Plain to Crescent (MP 25.3 to MP 30.6) Jefferson County, CO 14 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Amtrak The westbound Zephyr heads west through a cut that is known as "Old Tunnel 17". When the Moffat Route was originally be built in the early 1900s, the tunnel presented a lot of geologic problems, includes frequent cave-ins. The tracks were rerouted around a shoofly outside of the tunnel. That shoofly is now beneath all the pine trees on the outside of the cut in this shot. Old Tunnel 17 was finally daylighted, and the tracks were moved to their current alignment, now moving through a cut instead of a tunnel. While Tunnels 9 and 28 were daylight quite awhile after the route had been in operation, they retained their numbers. Since "Old Tunnel 17" had issues from the beginning of construction, at was ultimately bypassed, the next tunnel to the west was numbered Tunnel 17 from the start.

This area is known as South Draw, and is absolutely one of the highlights of riding the Zephyr (or other passenger trains) on the Moffat.

The tunnel allows the tracks to leave South Draw, and connect with the open valley at Crescent, near Gross Reservoir. The westbound Zephyr is approach a clear (green) intermediate signal just east of Tunnel 17 on the approach to Crescent. Email Questions or Comments to the Webmaster or add a comment to the picture. Photo ID: 112716 Date Shot Photo By Tuesday, July 1, 2025 Kevin Morgan Location Times Viewed Crescent (5,550 ft) Boulder County, CO 9 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Amtrak Near the east end of Crescent, the Zephyr is on the main and moving west at track speed. There are several residences in the area that, if you don't mind living a very rural life, would be quite nice. Email Questions or Comments to the Webmaster or add a comment to the picture.

The tracks come out of a nice little cut from the east, where the House Track starts. There are several nice (and right now, green) deciduous trees in the area as well.

Construction on the dam has been ongoing four about four years, as the dam is being raised by over 100 feet, a project that will triple the capacity of Gross Reservoir.
